"SB800"


Barcelona, VE
          

Hola amigos, tengo una duda, poseo una d200 con un flash sb800 y al aumentar el EV en el flash el rango de distancias de la pantalla del mismo disminuye lo cual me confunde, alguien podria explicarme en realidad por que sucede esto, gracias

A informação do monitor do flash é sobre a distancia possível de trabalho. Se você aumenta a potencia que o flash deverá entregar (o que acontece por ter especificado +1 EV), a distancia possível de trabalho cai.

The information on the flash screen is about the effective distance the flash unit can work. If you increase the power demand from the flash unit (you did that when specify +1 EV), the workable distance will decrease.

Creo que la idea ya está dicha. La potencia del Flash es una dada: Según lo compres. Si quieres más luz, la distancia debe caer.



Espero que en el diagrama se explique eso.

Suerte con tus fotos.

Misterpay,

Sigue:

http://support.nikonusa.com/app/answers/detail/a_id/9910/~/flash-exposure-compensation-and-working-distance

Recuerde que en TTL su cámara y flash se comuniquen juntos.

Cuando diría a su cámara para aumentar la compensación (no importa en cual modo- la cámera o en el flash) usted diría a la cámara que la escena esta bajo expuesto. Por eso, su cámara y flash hablan juntos, y deciden entonces que la distancia posible para exponer la escena correctamente ha efectivamente diminuido también y en seguida se comuniquen este información en la escala de distancias que usted se ve en el reves del flash.

en parte dice el articulo:
Cuando se aumenta la FEC "+", la intensidad de la luz se ha incrementado y la distancia de trabajo se ha reducido. Cuando se reduce la FEC "-", la intensidad de la luz se ha reducido y la distancia de trabajo se ha incrementado, como se refleja en la pantalla LCD del flash.
